thanks

Two remarks:

1) In usage(), one could replace show_usage and show_version by something
like

          fprintf(stdout, "\nType \"dvipdfmx --help\" for details.\n");

Then mistakes on the command line don't automatically produce the
help screen anymore. I sometimes find it annoying that simple typos
fill most of the screen with text.

2) What about extractbb? Should we have the same options there?

Best,
